Firebug doesn’t display my javascript? can't find the error
提问by YoniGeek
well I want to debug some script with Firebug, (cause I can't see anything in the browser window) but when I click the script tab in Firefox it gives me the error message:
好吧，我想用 Firebug 调试一些脚本（因为我在浏览器窗口中看不到任何内容）但是当我单击 Firefox 中的脚本选项卡时，它给了我错误消息：
If tags have a "type" attribute, it should equal "text/javascript" or "application/javascript". Also scripts must be parsable (syntactically correct).
如果标签有一个“type”属性，它应该等于“text/javascript”或“application/javascript”。脚本也必须是可解析的（语法正确）。
What am I doing wrong?
我究竟做错了什么？
Here's my code:
这是我的代码：
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script src="jquery-1.7.1.js"></script>
<script type="text/javascript">
$(function() {
/* fix: “close” the value of i inside createFunction, so it won't change */
var createFunction = function(i) {
return function() { alert(i); };
};
for (var i=0; i<5; i++) {
$('p').appendTo('body').on("click", createFunction(i));
}
})();
</script>
</body>
</html>

You must leave out the last parenthesis, I guess the code should run on dom ready?
你必须省略最后一个括号，我猜代码应该在 dom 上运行就绪？
<script type="text/javascript">
$(function() {
/* fix: “close” the value of i inside createFunction, so it won't change */
var createFunction = function(i) {
return function() { alert(i); };
};
for (var i=0; i<5; i++) {
$('<p>').appendTo('body').on("click", createFunction(i));
}
});
</script>
See herefor how to make code running on dom load with jquery.
请参阅此处了解如何使用 jquery 使代码在 dom 负载上运行。

In my Case I have opened firebug in other tab, So it was showing me this error.
在我的案例中，我在其他选项卡中打开了 firebug，所以它向我显示了这个错误。
- Solution : I have closed one tab and refreshed the page. and it was working :)
- 解决方案：我关闭了一个选项卡并刷新了页面。它正在工作:)

Remove parenthesis after }):
删除括号后})：
$(function() {
/* fix: “close” the value of i inside createFunction, so it won't change */
var createFunction = function(i) {
return function() { alert(i); };
};
for (var i=0; i<5; i++) {
$('p').appendTo('body').on("click", createFunction(i));
}
}); //here is the modification
